The most frequent, but fairly simple option for damage to the tile coating is to detach the tiles from the base. There may be several reasons: violation of the installation technology, moisture, temperature, mechanical damage, etc. In most cases, to eliminate the designated problem, it is advised to carefully remove the tile, remove the solution from its surface and from the base (wall or floor) under the tile and lay it in the same place with the help of glue for tiles. But, as practice testifies, in 90 cases out of 100, this tile will be damaged (crack) while removing the solution from it or will be a little bulging compared to others, if the solution is not completely removed.
